APPLICATIONS
The TG H74c, designed for wireless operation, offers plenty of
freedom of movement. With a supercardoid polar pattern and
compensated proximity effect, it is particularly suited for musical
and theatre applications. Highly adjustable, exceptionally discreet,
mountable on both sides and impressively small and rugged – what
else could you want from a headset microphone? Available in both
black and tan.
